“Bachelor” fans could learn a thing or two about dating from this season’s arch villain, Tierra LiCausi.

Match.com relationship expert Whitney Casey says that the woman who fans have nicknamed “Tierrable” is actually working some very effective dating strategies.

“I think she’s smart in the ways of getting her man,” Casey tells The Post. “She does a great job of making him feel loved and happy. She’s doing what it takes.”

So far this season, “doing what it takes” has involved sneaking away from the other women to get extra alone time with “Bachelor” Sean Lowe, getting injured (some believe she faked injury) twice for some sympathy and not bothering to make friends with the other women.

Sweet, attentive and open about her feelings when she is with Lowe, Tierra isn’t wasting her time on the hit dating show on drama with other women.

Tierra’s kamikaze style of dating that has earned her a spot in the final six, notes the show’s host, Chris Harrison, is reminiscent of “Bachelor” lightning rods, Vienna Girardi and Courtney Robertson, both of whom won their men (for a short while, at least).

“The thing is with Tierra, Courtney and all of these girls is that they’re smart, and they’re good at what they do,” Harrison says. “This isn’t the first time they’ve done this. It’s their game, it’s the way they go about picking up men.

“It’s kind of kill or be killed and survival of the fittest and everyone else be damned.

“The funny thing is, and I think I’ll get hammered for saying this, it’s not like it’s less sincere. It’s not like Courtney didn’t fall in love with Ben [Flajnik], and it’s not like Vienna and Jake [Pavelka] weren’t I think, in love. But that’s just their way of finding it.”

Tierra’s competitors have called her “crazy,” “fake,” “cold,” “manipulative” and “two-faced.” But Harrison says that the behavior isn’t that different from what you’d see at a local bar on a Saturday night.

As for the Tierra haters, Casey says that the difference between real life and reality TV is that, on TV, the losers have a camera to complain to.

“When we go to the bar and we’re talking to the guy, other women are talking about us at their tables, “ she says. “We just don’t ever get to meet them.

“So, it’s happening everywhere. There just happens to be a camera on the group of women who are tearing apart Tierra.”

So, who is most likely to takes the Tierra-style, take-no-prisoners approach to dating?

Apparently, it’s New Yorkers.

“You don’t make it in New York by being nice to somebody and giving them your cab,” says Casey, who, not surprisingly, is a New Yorker herself.

“People who are highly competitive and successful date this way.

“Successful people typically date the exact same way as they live their lives.”
